As a trusted Pinion Nut Manufacturer in India, New Star Industries manufactures precision nuts that do far more than just clamp a joint — they set and maintain the exact bearing preload that keeps a pinion gear correctly aligned inside a differential or gearbox. Get that preload wrong, and the result isn't just a loose fastener, it's premature gear wear, noise, or drivetrain failure.
A pinion nut is tightened to a very specific torque that sets the bearing preload on the pinion shaft — too loose and the gear can shift under load, too tight and the bearings wear out early. We manufacture our pinion nuts in grades 8 and 10, strictly as per the customer's own drawing, in sizes from M18 to M45, so the fit and torque response are matched exactly to the gearbox or differential design.
✓ Precise Preload Control: Manufactured to consistent dimensional tolerance so bearing preload can be set accurately and repeatably during assembly.
✓ High Torque and Axial Load Capacity: Available in grades 8 and 10, built to withstand the high torque and axial thrust loads typical of drivetrain and transmission applications.
✓ Reliable Locking Under Vibration: Designed to hold its set torque through continuous drivetrain vibration, preventing gradual preload loss over the vehicle or machine's service life.
✓ Built to Customer Drawing: Every pinion nut is manufactured as per the customer's own specification, ensuring correct thread engagement and seating for the exact pinion shaft design.
✓ Consistent Batch Accuracy: Manufactured under controlled processes so that torque-to-preload behaviour stays consistent across every nut in a production run.
Pinion nuts from New Star Industries are widely used in automotive differentials, industrial gearboxes, and heavy machinery drivetrains, where maintaining correct gear alignment and bearing preload directly affects the performance and service life of the entire transmission system.
Since pinion nuts must match the exact preload and fit requirement of a specific gearbox or differential, New Star Industries manufactures them strictly as per customer drawing. Share your drawing with our team, and we'll manufacture to your precise requirement.
